Q_DECLARE_INCOMPATIBLE_FLAG - this seems like a useful macro, but I can't find any documentation on it.

[shavera]

Edit: It doesn't seem like this macro did what I hoped it would, under more inspection. Maybe there's a better way to set mutually exclusive options? </end edit>

Supposing I have flags that are mutually exclusive (say something can either be A or B, which I'd like to be named flags), this seems useful.

At the moment I'm doing something I think is a bit hacky

Enum Flag{
  A = 1,
  B = ~1
};
Q_DECLARE_FLAGS(Flags, Flag)

But the Incompatible flag option seems more like the right approach (given what I can kind of figure from the source code around the macro)
